Asteroids, Defender, Scramble, all familiar names to us slow machine freaks...
Trying to program them into 1K is like teaching a lizard to play billiards.
Good old Romik has a bash, and a good job it makes of it too. I wouldn't go

and should give ZX81 owners some idea of why memory expansion is de rigeur
in all the best circles.
Six of the nine programs are of the "shoot when you see the yellow of their
eyes" type, aliens zapped and capowed in various unspeakable ways. Squash is a
slow and flickering tennis type simulation, Sketch is a simple drawing program
which can produce copy on the ZX Printer, and Four Thought displays a grid
into which two players are supposed to place counters alternately, with the
aim of getting four in a row.
